type InputStreamReadFunc a
Arguments
| = Ptr Char | Buffer where to copy the read data |
| -> Word64 | Desired number of bytes to read |
| -> Ptr a | User data |
| -> IO Word64 | The number of bytes actually read |
Function to read data from the stream.
type InputStreamSeekFunc a
Arguments
| = Word64 | The position to seek to, from the beginning |
| -> Ptr a | User data |
| -> IO Word64 | The position actually sought to, or -1 on error |
Function to set the current read position.
type InputStreamTellFunc a
Function to get the current read position.
type InputStreamGetSizeFunc a
Arguments
| = Ptr a | User data |
| -> IO Word64 | The total number of bytes available in the stream, or -1 on error |
Function to get the total number of bytes in the stream.
data InputStream
Set of callbacks that allow users to define custom file streams.
